METAL SHINGLE.

To all whom it may concern:

Be it known that I, OSCAR F. JAooBsoN, a citizen of the United States, residing in Garfield township, in the county of Clay and State of Kansas, have invented new and useful Improvements in Metal Shingles, of which the following is a specification.

My invention relates to metal shingles for application to roofs ofbuildings and for other purposes and is designed to prevent water or other liquid from flowing or leaking through between the overlapping ends of the shingles. I attain these objects by means of the construction illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of a series of shingles constructed in accordance with my improved method and fitted together as when on the roof of a building; Fig. 2, an end elevation thereof; Fig. 3, a side elevation of a longitudinal section through the middle portion of the shingles; Fig. 4, a side elevation of a longitudinal section in line with the edge of the projection 8, and Fig.

-5, a detail 'vlew in perspective of my improved shingle.

Similar numerals of reference indicate like parts throu bout the several views.

Full length s ingles are indicated by the. numeral 1, the bottom half-course by 1 and the top half-course by 1".

2 is the edge of a raised seam; 3, the flange at the outer edge of each shingle; 4, a slit cut in the edge thereof at a proximately midway .of its length; 5, t e end folded under and 6, the end folded over; 7, the pro'ections formed in beveling the ends of the olded part 6, such beveling being for the purpose of facilitating joinlng; 8, the projections formed in cutting in to make the folded end 5.

It is common to join metal shingles by longitudinal ridges and grooves, forming Specification of Letters Patent.

what is known as raised seams and leav-- interlocked and hammered together, thus forming a reasonably tight joint to resist the back flow and prevent leaking.

In laying my improved shingles the bot tom course is laid in the usual manner with the overlap fold 6 uppermost at the u end of the shingle. laid that the underlap fold 5 engages the overlap fold 6 and the shingles pulled snugly into position with the end of the overlap 6 engaging the slot 4 with the sides of each alternate layer exposed and of the other covered for approximately half their length. Thenailing of the shingles is done in the usual manner by driving the nails through the flanges 3 only wherethey will be covered by the overlapping portion of the next course; At the proper time all seams and joints are securely pressed or hammered together inthe usual manner.

Having thus described my invention what I claim as new and desire to secure by Letters-Patent is A metal shingle having one of its ends folded over and its other end folded under per- The next course is so so that each layer may be interlocked with I the layer abutting therewith, said shingle being provided with slits midway thereof which extend in from the sides thereof, the portion above said slits being adapted to engage over the turned over portion of an adjacent shingle and the portion below said slits being adapted to engage under said turned over portion of said adjacent shingle.
